OOM due to build of of iterate executions during bulk message consumption - asyncWakeup called
excessivly
---------------------------------------------------------------------------------------------------------

                 Key: AMQ-2483
                 URL: https://issues.apache.org/activemq/browse/AMQ-2483
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.3.0
            Reporter: Gary Tully
            Assignee: Gary Tully


when consuming a large of messages,the method:asyncWakeup() is invoked
crazily,so the executor has a great deal of  runnable that callback Queue.iterate(), but
Queue.iterate() is much slower than the increasing of runnable in the
executor. this result in OOM.

avoid to invoke the method:asyncWakeup()  frequently???
